  • Abstract
    A relationship is described between the intermodulation distortion (IMD) performance of a parallel MESFET switch to the device´s experimentally extracted higher order derivatives. As the third-order Ids(Vgs, Vds) Taylor-series coefficients support a non-optimum linearity in cold FET operation (VDS=0 V), a small drain-to-source voltage ´sweet spot´ has been found for IMD reduction, giving a useful bias point for highly linear switching applications without degrading attenuation.
